为了评价和预测与石油产品、燃油接触而工作的橡胶制品,以及燃油本身的使用性能的变化,必须采用综合方法定量测定由橡胶迁移到燃油中的组分。耐油橡胶中的能够扩散到燃油中去的配合剂含量变化范围较宽,从10％(增塑剂)到1～0.5％(防老剂-2,硬脂酸等)。硫化胺中硫黄和促进剂的含量(促进剂DM,M)不超过0.1％,因为它们在硫化过程中被消耗,并发生了一系列变化。橡胶和燃油的实际重量比是1:40,所以橡胶中的这些组分在燃油中的浓度,即使在被完全抽提的条件下,仍然是很小的(0.02—2.00毫克/厘米~3)。为了测定抽提出的配合剂,需要选择一种能使配合剂与燃油主体以及配合剂之间都相互分离的方法。有关(气液色谱)和TCX(薄层色
In order to evaluate and predict changes in the performance of rubber products working in contact with petroleum products and fuels and their own use of fuels, an integrated approach must be employed to quantitatively measure the components migrating from rubber to fuel. The amount of compounding agent that can diffuse into the fuel oil varies widely from 10% (plasticizer) to 1-0.5% (Antioxidant-2, stearic acid, etc.). Sulfur sulfide amine sulfur and accelerator content (accelerator DM, M) does not exceed 0.1%, because they are consumed in the curing process, and a series of changes. The actual weight ratio of rubber to fuel is 1:40, so the concentration of these components in the fuel in the fuel, even under fully extracted conditions, is still small (0.02-2.00 mg / cm3) . In order to determine the extracted formulation, one needs to choose a method that will separate the formulation from the fuel body and the formulation.
